In my opinion, that's just plain wrong. But, a sadly common
misunderstanding. We just never agreed on what the difference was between a
wordlist and a phrase and we're stuck with that misunderstanding.
The good news is that we nailed down that semantic in CQL for SRW/U. A word
list is just a list of words. The relation attribute defines the implicit
operator between the words. Wordlists can have implicit AND's OR's and
PROX's, depending on the relation.
